"Webrecollements to different levels of derived categories, see [1, Theorem III]. Moreover, by [1, Section 5] the height of the ladder measures how far an algebra is from being derived simple [37], i.e.its derived category is not the middle term of a non-trivial recollement with outer terms derived categories of algebras.

WebThe crucial point of derived categories is that D ( 𝒞) knows how to subtract or annihilate objects of 𝒞. 𝒞, being abelian, is an additive category, but need not have a notion of subtraction. In order to get that, one needs to make use of the translation functor. (6) T: D ( 𝒞) → D ( 𝒞) which shifts all the indices n of the ...
